title: Objective measures of laryngeal imaging: what have we learned since Dr. Paul Moore.
abstract: Dr. Paul Moore pioneered the use of high-speed cinematography for observation of normal and abnormal vocal fold vibrations during phonation. His analysis of the glottal area waveform, opening and closing speed index, and open quotient from the high-speed films were labor intensive but relevant today. With advances in digital image capture and automated image extraction techniques, stroboscopy and high-speed images of vocal fold vibration may be analyzed with objective measures. Digital high-speed image capture in color is now clinically practical at high resolution. Digital kymography now allows analysis of the vibratory waveform from each vocal fold. Serial capture and comparison can document changes in vibratory function with treatment. Quantification of vocal fold vibration using such techniques is now practical. This is a review of vocal fold vibration capture and analysis techniques since Dr. Moore.
